"NettetThe spectral linewidth of standard Fabry–Perot semiconductor lasers is typically on the order of 100 MHz. For many applications, such as holography, spectroscopy, and coherent optical communication systems, these broad linewidths are unsatisfactory. The main difficulty of obtaining narrower linewidths in semiconductor lasers is that there is ... " - Led linewidth

Nettet12. apr. 2024 · We further found that the homogenous linewidth is broadened upon introduction of surface terminations. Thus, our study suggests a possible LED-performance degradation mechanism due to surface termination, and thereby proposes guidelines for enhancing the light-emission properties of nanostructured MHPs. NettetLaser linewidth is generally an issue for only very long transmission systems in the 1550-nm window or for systems that launch high power into the fiber. Lasers that are used in highly dispersive systems — e.g., >6000-ps/nm dispersion — must have narrow linewidths to avoid degradations that result from phase-to-amplitude conversion noise ( Chraplyvy …
